Abstract

Electrochemical machining (ECM) has established itself as a major machining process which can be used as an alternative to conventional methods for machining hard materials and complex contours without the hindrance of residual stresses and tool wear. ECM has extensive applications in Aerospace, Petroleum, Automotive, Medical, Textile AND Electronic Industries. Material Removal Rate (MRR) is one of the important process parameters in ECM, because it is one of the determining factors in the process decisions. The project is an attempt to check the design parameters such as material removal rate (MRR), overcut diameter and overcut depth of AISI P20 work piece by using a rotating copper U-tube tool. Four parameters were chosen as process variables: Voltage, Feed Rate, Electrolyte concentration and Tool diameter. The experimental results show that the material removal rate (MRR), increase with increasing feed, voltage and electrolyte concentration but decreases with increasing the tool diameter, and for both overcut depth and overcut diameter they increases with increasing feed ,voltage and electrode diameter but decreases with increasing electrolyte concentration. To identify the optimal parameter setting in the experiment Grey relation grade (GRD) was also applied.
